EDWARD F. MAYBAUM, OF N EV YORK, N. Y.

VEHICLE-WHEEL.

Application filed September 1, 1908. SeriaLNo. 451,741.

To all whom it may concern.'

Be it known that I, EDWARD MAYBAUM, a citizen ot the United States of America, and a resident of the borough of Manhattan, city, county, and State of New `York, have invented certain new and useful Improvements vin Vehicle-"Wheels, ot' which the :tolloiving is a specification. i

This invention relates to improvements in vehicle wheels. and especially to improvements in Wheels of power-driven vehicles, such as automobiles, auto-trucks, and other power-driven vehicles. I f

lt is the purpose of the invention to pro videa resilient Wheel, Without pneumatic tires, but which will possess all the. advantages ot' Wheels with such tires Without their serious and inherent disadvantage of liabil-4 ity to'collapse through punctures, blow-outs, and a variety ot' other accidents. Such, indeed is the liability of pneumatic tires to failure from various causes, that it is a serious impediment and danger to the use of automobiles, and .the tires are a constant source of expense. Thus far, however, no satisfactory substitute for pneumatic tires has'beendcvised; and it is the purpose of this" invention to providesuch a substitute.

My invention also aims to provide great si rength ot. construction, and security against undue creeping ot' the tires or rims, While also providing a great and satisfactory revvhich insures smooth and comfortable running of the machine and the least practicable Wear and tear ot' its parts. u

Referring to the drawings, which accompany the specification to aid the description, Figure 1 is an elevation partly broken ot a ivheel equipped with the invention; Fig. 2 a vertical cross section-of a modification ot the wheel. wherein the spokes are provided with tivo sets of springs; Fig. 3 is an edge or it'are elevation of the Wheel; and Fig. `l.- is an enlarged broken section and elevation ot' certain parts of the modifica- Iion shown in Fig. 2; .ligz 5, is a detail on enlarged scale of the washer, spring plate, and' adjacent parts: Fig. o is a sectional detail. on a large scale, ot a inoditicalion ivhoro in the ivheclis fixed ou the axle and the axle. revolves ina hearing.

The ivhcel may turn upon its axle 30. any suitable ball bearing being provided. or it may be lixed upon said axle, and the axle. inay tnrn`in suitable bearings. The hub 1li of said Wheel is provided with any suitable number of hollow spoke bodies 12, which mayA be integral with said hub 13, or secured to said hub in any suitable manner, and said spoke bodies and hub will preferably be of metal possessing great tensile strength. The annular gear 15 is preferably bolted to lugs 16 of said spoke bodies. In the outer endof each said spoke body 12 is a radially perforated block 18, pivotally mounted in its spoke body so as to be capable of a slight but sufficient oscillation in the plane of rotation of the Wheel; 19-19 being the pivot bolts of said block 18; and to better exclude` dust I provide each block 18 with a boss 21 shaped on an arc ot" a circle struck from the center of oscillation of the spoke 23, and truly fitting its spoke body 12.

A groove 17 for a suitable spoke lubricant, as graphite, is also in each block 18. Through the bore of each block 18 Works a radial spoke 23, normally pressed Aoutwardly by a powerful spring 24, preferably arranged as shown with its outer end bearing on the flanges of the rim l, and its inner end bearing on the centrally perforated closing spring plate 2G. A dust-preventing annular 'asher 27. of leather or any suitable material, is held in place in the recessed end of each block 18 b v said closing plate 2o, and said spokes 23 Work through said Wash,- crs 27. with dust-tight tit. I prefer to place another powerful spring 29 on the inner part et" each said spoke 23, arranged between the inner ends of said spokes and of said blocks 18 and so as to resist any tendency to move the said spokes 23 outwardly beyond normal position, the result of the action of both sets of said springs 24 and 2T, being to give very perfect resiliency to the wheelthat is. to its riin'and tire. The inner ond ot each said spoke 23 is provided with a roller 2S adapted to bear on the inner wall of itsl corresponding spoke body 12 when any slight deflection of the spoke ooeurs through tendency of the tirrto creep. so as to prevent undue creeping oi the tire and rini. while allowing of sufficient radial v .movement of said spoke 25% to insure' the" proper resiliency of the ivhoel. 'ttheirv outer ends thil said spokes 2li are each cured to the [langes l ot the rinis i b v bolts 5 and jam nuts (i. bushings T properly distaneing the said flanges .Jr-4. so as to prevent their unduly binding' on the said spokes 23. The halves of said rini l are preferably shape in the side curved, as seen in Figs. 2 and 4, and the curved outer edge of each said half of the rim enters an annular groove 3 of proper of the solid tire 2, said tire being formed of rubber or of any .other suitable'material; cross-bolts 10,'W-hich eX- tend through said tires and sidesfo" the rim firmly holding the tire 2 in the rim and the parts of the rim together.n By the aforesaid construction of the rim in two parts, with the tire and bolts as described, I provide for theready removal and replacing of tires, and attain a construction of great strength and durability.

In operation, it will be understood that as the W'ieelruns overthe ground, any joltroad or any other cause will be taken -up by the resiliency of the Wheel, Whichis insured by the spring-controlled radial movement 4of the spokes hereinbefore described, so that the vehicle runs With great smoothness and comfort to the occupants; While the combination of the strong hollow spokebodies l2 With the spokes 23 and the rollers 28 insures against any undue creeping of the tires, Without diminishing the resiliency ofthe Wheels. y

t will of course be understood that the hub, spoke bodies and spokes may be constructed of any suitable material, and preferably of a metal having great tensile strength; that the rollers 28 may be of hard Yrubber or any other suitable material, the

tires 2' of any rubber, rubber compositions or any other material -suitable for tires, and generally that all parts of the Wheel may be 'constructed of such materials as'may be adapted to the particular use to Whichthev. wheel is to be put; and it will also be under` stood that various be modiiied Without departing sential features.

N 0W having described my improvements I claim as my inventionl. In a vehicle Wheel, the combination of' a rim, a hub,hollow spoke bodies rigid thereon, spring-controlled spokes radially movg able in said spoke 'bodies and connected at fromI its esparts of the invention may their outer ends to said, rim, and rollers ou said spokes adapted to bear against.v the Walls of said spoke bodies to limit the deilection of said spokes, substantially as described'.

2. In a vehicle Wheel, the combination of a hub, hollow spoke bodies -rigid thereon, guide blocks pivotally mounted in said spoke bodies, spokes radially movable in said blocks, and means on said spokes adapted to bear on. theinner Walls oi,l said spoke bodies and limit the deflection of-said spokes, substantially as described. g

3.. The combination in a. vehicle Wheel, of a rim and a tire, a hub, spoke bodies rigid thereon, blocks pivotally mounted in said spoke bodies, spring-controlled .spokes radially movable in said vblocks and connected at their outer ends to said rim, and rollers on the inner ends of said spokes adapted to bear against the Walls of saidspoke bodies and limit the creeping of the rim and the tire, substantially as described.

Ina vehicle Wheel, the combination with lixed spoke bodies and radially movable spokes of guide lblocks `for said spokes mounted in said spoke bodies and provided with dust preventing bosses, substantially as described. f

5. The combination with the fixed spoke bodies and movable spokes of a vehicle Wheel, of blocks through which said` spokes Work, dust preventing Washers, `and closing.

plates, substantially as described.

6. The combination in -a vehicle Wheel, of a hub; a rim-and a tire, rigid spokes on said hub, radially movable springcontrolled spokes guided by saidrigidspokes and pivotally connected at their rim, and havin@ rollers on their inner ends adapted to limit the deflection of said radially movable spokes, substantially as described. l
